Fitting for the pivoting support of a window sash or door leaf

Abstract

In order to support a window sash on a fixed frame in such a way that it can pivot around a vertical axis, a horizontal support arm is provided which is connected with a frame-side pivot bearing by means of a support angle, the vertical leg of which grips behind a support plate. An adjusting device which acts in the horizontal direction to change the distance between the sash and the axis of the pivot bearing is not placed in the region of the support angle, but rather at the end of the support arm which is away from the pivot bearing, and acts between the support arm and a filler piece which is fastened in the groove channel of the sash.

What is claimed is:  
     
       1. A fitting for the pivoting support on a frame of an associated member such as a window sash or door leaf that defines a plane, the associated member having at least one vertical groove area and at least an upper corner, which comprises: 
       a pivot bearing which has a vertical axis of rotation and attaching structure for attachment to the associated frame, and a movable support piece including a support plate which is bent at a right angle to the plane of the associated member and which is dimensioned and configured for the engagement between the at least one vertical groove area, an essentially horizontal support arm which is connected with the support plate by means of a support angle, the vertical leg of which grips behind the support plate, a filler piece dimensioned and configured for insertion into the groove channel of at least the upper horizontal groove area, the filler piece being fastened in the groove channel, a connection between the support arm and the filler piece guiding the support arm with limited movability in the vertical direction, the support arm being supported against forces acting perpendicular to the plane of the member, and an adjusting device which acts upon the support arm and in the horizontal direction to change the distance between the member and the axis of the pivot bearing, wherein the support angle is formed onto the support arm as one piece, and the adjusting device is placed at a location on the support arm which is at a distance from the pivot bearing, and acts between the support arm and the filler piece.  
     
     
       2. A fitting according to  claim 1 , characterized in that the adjusting device comprises an adjusting screw which is supported on the end of the support arm away from the pivot bearing in such a way that it can pivot but cannot move axially, and which engages in a threaded bore in the filler piece. 
     
     
       3. A fitting according to  claim 1 , characterized in that the filler piece comprises on its upper side one or more projections which protrude upward, and each projection engages in a section provided on the support arm in such a way that the support arm is movably guided on the filler piece in the vertical direction and in its longitudinal direction, and is supported in positive fashion against forces acting perpendicular to the plane of the member. 
     
     
       4. A fitting according to  claim 2 , characterized in that the filler piece comprises on its upper side one or more projections which protrude upward, and each projection engages in a section provided on the support arm in such a way that the support arm is movably guided on the filler piece in the vertical direction and in its longitudinal direction, and is supported in positive fashion against forces acting perpendicular to the plane of the member.
